I was interested to see how Zenwalk differs from Slackware, and after reading on their web site that version 2.01 is 'the biggest jump in Zenwalk evolution since the beginning of the project', I wanted to see how far Zenwalk has come since it was reviewed here as MiniSlack.

I use zenwalk1.3 in my power plant historian product, as the OS.
It is very fast and stable. The best thing for developers, every tool and library like gcc and GTK+ is ready. if I use Ubuntu, I have to grab them one by one.
Please take a look at zenwalk and my gas turbine historian at http://www.leiosoft.com/products.htm
